TECHNICAL BACKGROUND

Wireless communication networks provide wireless data services to wireless user devices. Exemplary wireless data services include machine-control, internet-access, media-streaming, and social-networking. Exemplary wireless user devices comprise phones, computers, vehicles, robots, and sensors. The wireless communication networks have Radio Access Networks (RANs) which exchange wireless signals with the wireless user devices over radio frequency bands. The wireless signals use wireless network protocols like Fifth Generation New Radio (5GNR), Long Term Evolution (LTE), Institute of Electrical and Electronic Engineers (IEEE) 802.11 (WIFI), and Low-Power Wide Area Network (LP-WAN). The RANs exchange network signaling and user data with network elements that are often clustered together into wireless network cores. The RANs are connected to the wireless network cores over backhaul data links.

The RANs comprise Radio Units (RUs), Distributed Units (DUs) and Centralized Units (CUs). The RUs are mounted at elevation and have antennas, modulators, signal processor, and the like. The RUs are connected to the DUs which are usually nearby network computers. The DUs handle lower wireless network layers like the Physical Layer (PHY) and Media Access Control (MAC). The DUs are connected to the CUs which are larger computer centers that are closer to the network cores. The CUs handle higher wireless network layers like the Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP). The CUs are coupled to network functions in the network cores. The network cores execute the network functions to provide wireless data services to the wireless user devices over the RANs. Exemplary network functions include Access and Mobility Management Functions (AMFs), Authentication Server Functions (AUSF), and Unified Data Managements (UDMs).

Authentication entails the exchange of data between a wireless user device and a wireless communication network so the network can confirm the identity of the wireless user device. When the wireless user device attaches to the network core over the RAN, the wireless user device registers with an AMF to perform authentication. The AMF interacts with the AUSF and UDM to generate a random number and an expected result. The wireless user device is given the random number to hash with its secret identity code and return the expected result. The AMF matches the two expected results to authenticate the wireless user device. Responsive to the authentication, the wireless user device receives wireless data services from the network core.

Quantum authentication uses the quantum properties of photons to generate secret identity codes. To generate a secret identity code, a quantum device encodes a photon with various quantum states like polarization and spin. The quantum device transfers the encoded photon to another quantum device over an optical interface like a quantum channel. The other quantum device determines the quantum states of the photon. The two quantum devices exchange data to select matching quantum states. The matching quantum states comprise the secret identity code for the two quantum devices.

Unfortunately, the AMFs and AUSFs do not effectively use quantum authentication for the wireless user devices. Moreover, the UDMs do not efficiently generate secret identity codes for the wireless user devices using quantum authentication.

FIG. 2 illustrates an exemplary operation of wireless communication network 100 to perform quantum authentication for wireless UE 101. The operation may vary in other examples. Network quantum circuitry 126 generates and transfers qubits to UE quantum circuitry 106 (201). UE quantum circuitry 106 receives and processes the qubits (202). In response, UE quantum circuitry 106 determines polarization states for the qubits and exchanges cryptography information with network quantum circuitry 126 (203). For example, UE quantum circuitry 106 may exchange quantum information with network quantum circuitry 126 that indicates the measured polarizations of the qubits.

FIG. 3 illustrates an exemplary operation of wireless communication network 100 to perform quantum authentication for wireless UE 101. The operation may vary in other examples. Network quantum circuitry 126 generates qubits. The qubits may comprise photons, electrons, atoms, or other types of particles that can transfer quantum information. For example, quantum circuitry 126 may polarize photons with different polarization states to generate the qubits. Network quantum circuitry 126 transfers the qubits over quantum link 111 to UE quantum circuitry 106. UE quantum circuitry 106 processes the qubits and responsively determines polarization states for the qubits. Typically, UE quantum circuitry 106 selects a measurement basis for each qubit and determines the polarization states for the qubits using the selected measurement bases. UE quantum circuitry 106 exchanges cryptography data that indicates the determined polarization states with network quantum circuitry 126. Network quantum circuitry 126 exchanges cryptography data that indicates the selected polarization states with UE quantum circuitry 106.

Network quantum circuitry 126 and UE quantum circuitry 106 generate cryptography keys based on the polarization states and the cryptography information. For example, UE quantum circuitry 106 and network quantum circuitry 126 may compare the polarization states determined by UE quantum circuitry 106 with the polarization states selected by network quantum circuitry 126 to derive a quantum-based authentication key. UE quantum circuitry 106 transfers the cryptography keys to UE network circuitry 105. Likewise, quantum circuitry 126 transfers the cryptography keys to authentication circuitry 125.

UE network circuitry 105 processes the cryptography keys to generate authentication data. The authentication data comprises hashes, digital certificates, or another type of authentication data to authenticate UE 101 with network data center 121. For example, UE network circuitry 105 may receive an authentication challenge from network authentication circuitry 125 and use the quantum key to resolve the authentication challenge and generate authenticate data that indicates the resolution. UE network circuitry 105 wirelessly transfers the authentication data to network authentication circuitry 125 over the wireless access point. Network authentication circuitry 125 authenticates UE 101 based on the authentication data and the cryptography keys. For example, network authentication circuitry 125 may receive authentication data that indicates an authentication result from UE 401 and use its quantum-based cryptography key to verify the authentication result supplied by UE 401.

FIG. 4 illustrates Fifth Generation (5G) communication network 400 to perform quantum authentication for UEs 401 and 402. 5G communication network 400 comprises an example of wireless communication network 100, although network 100 may differ. 5G communication network 400 comprises 5G UEs 401-402, quantum links 411-412, 5G RAN 420, drone landing platform 430, vehicle support station 440, and 5G network core 450. 5G UE 401 comprises a quantum capable unmanned aerial drone. 5G UE 402 comprises a quantum capable vehicle. 5G RAN 420 comprises 5G Radio Unit (RU) 421, 5G Distributed Unit (DU) 422, and 5G Centralized Unit (CU) 423. Drone landing platform 430 comprises edge Unified Data Management (UDM) 431. Vehicle support station 440 comprises edge UDM 441. 5G network core 450 comprises Access and Mobility Management Function (AMF) 451, Session Management Function (SMF) 452, User Plane Function (UPF) 453, Authentication Server Function (AUSF) 454, UDM 455, and Policy Control Function (PCF) 455. Other network functions and network elements are typically present in 5G network core 450 but are omitted for clarity.

UE 401 detachably couples to edge UDM 431 in drone landing platform 430 over quantum link 411. Quantum link 411 comprises an optical interface, metallic links, glass fibers, a vacuum, and/or some other type of medium that can transfer or some other type of quantum capable interface that can transfer qubits between UE 401 and edge UDM 431. UE 401 authenticates with drone landing platform 430. For example, UE 401 may wirelessly communicate with drone landing platform 430 to authenticate itself via Fifth Generation Authentication Key Agreement (5G AKA), Extensible Authentication Protocol (EAP), or some other type of authentication protocol. In some examples, UE 401 may have pre-authenticated with 5G core 450. For example, 5G network 400 may configured UE 401 with a unique ID that indicates its identity and quantum capability, and UE 401 may use this unique ID to authenticate itself with drone landing platform 430 to initiate quantum authentication. In response to the authentication, edge UDM 431 initiates a Quantum Key Distribution (QKD) procedure with UE 401. The QKD procedure comprises QKD protocols like BB84 protocol, an E91 protocol, or another type of QKD protocol. Edge UDM 431 generates qubits for UE 401. The number of qubits generated by edge UDM 431 is not limited. Edge UDM 431 selects a polarization basis for individual ones of the qubits and polarizes the qubits using their selected polarization bases. Typically, edge UDM 431 selects either a vertical or horizontal polarization basis for each of the qubits. A vertically polarized qubit may comprise a vertical sinusoidal plane electromagnetic wave and a horizontally polarized qubit may comprise a horizontal sinusoidal plane electromagnetic wave. Edge UDM 431 transfers the polarized qubits to UE 401 over quantum link 411. The qubits may comprise entangled or non-entangled qubits. For example, edge UDM 431 may entangle pairs of photons and transfer one of the photons from each entangled pair to UE 401.

UE 401 receives the qubits from edge UDM 431. UE 401 selects a measurement basis for individual ones of the qubits received from edge UDM 431. For example, UE 401 may select a rectilinear measurement basis for a first qubit and may select a diagonal measurement basis for a second qubit. UE 401 determines the polarizations of the received qubits using the corresponding measurement basis for each of the received qubits. UE 401 wirelessly indicates the determined polarizations of the received qubits to edge UDM 431. Edge UDM 431 wirelessly indicates the polarizations it selected for each of the transferred qubits to UE 401. Edge UDM 431 and UE 401 generate an authentication key for UE 401 based on the determined polarizations of the received qubits and the selected polarizations for the transferred qubits. Typically, UDM 431 and UE 401 derive the key based on the qubits where the polarizations for the transferred qubits matched the determined polarizations for the received qubits. UDM 431 transfers the authentication key for UE 401 to UDM 455 over a secure channel. The secure channel could be an encrypted data link, although other forms of private communication including hand/drone delivery are possible.

To generate communication keys, edge UDM 431 initiates another QKD procedure with UE 401. Edge UDM 431 generates additional qubits for UE 401. Edge UDM 431 selects a polarization basis for individual ones of the additional qubits and polarizes the additional qubits using their selected polarization bases. Edge UDM 431 transfers the additional polarized qubits to UE 401 over quantum link 411. UE 401 receives the additional qubits from edge UDM 431. UE 401 determines the polarizations of the additional qubits. UE 401 wirelessly indicates the determined polarizations of the additional qubits to edge UDM 431. Edge UDM 431 and UE 401 generate communication keys for UE 401 based on the determined polarizations of the additional qubits. UDM 431 transfers the communication keys for UE 401 to UDM 455 over the secure channel. UE 401 detaches from drone landing platform 430 and moves to another location.

UE 401 wirelessly attaches to RU 421 and transfers attachment signaling to CU 423 over RU 421 and DU 422. CU 423 establishes a Radio Resource Control (RRC) connection with UE 401. CU 423 transfers a registration request for UE 401 to AMF 451. AMF 451 transfers an identity request for UE 401 in Non-Access Stratum (NAS) signaling to CU 423. CU 423 forwards the identity request to UE 401 over DU 422 and RU 421. In response, UE 401 indicates its identity to CU 423 over RU 421 and DU 423. CU 423 forwards the identity indication for UE 401 to AMF 451. AMF 451 selects AUSF 454 to authenticate UE 401 for wireless services. AMF 451 transfers an authentication request for UE 401 to AUSF 454.

AUSF 454 selects UDM 455 to authenticate UE 401. AUSF 454 requests authentication keys for UE 401 from UDM 455. UDM 455 transfers authentication data for UE 401 to AUSF 454. The authentication data indicates the quantum derived authentication key for UE 401. AUSF 454 uses the quantum derived authentication key for UE 401 and a random number to generate an expected result. AUSF 454 transfers the random number and the expected result for UE 401 to AMF 451. AMF 451 transfers the random number for UE 401 to CU 423 in NAS signaling. CU 423 forwards the random number to UE 401 in NAS signaling over DU 422 and RU 421. UE 401 hashes the random number with its quantum derived authentication key to generate the same expected result. UE 401 transfers the expected result to CU 423. CU 423 forwards the expected result to AMF 451. AMF 451 matches the two expected results to authenticate the identity of UE 401.

Responsive to the authentication and authorization, AMF 451 requests UE context for UE 401 from UDM 455. UDM 455 transfers UE context for UE 401 to AMF 451. The UE context comprises the quantum communication keys, Quality-of-Service (QoS) metrics, default slice identifiers, and default network addresses in accordance with the roaming agreement. AMF 451 interacts with PCF 456 to retrieve service policies for UE 401. AMF 451 selects SMF 452 to establish a Protocol Data Unit (PDU) session for UE 401 based on the UE context and the service policies. SMF 452 interacts with UPF 453 to establish the PDU session for UE 401. SMF 452 transfers session context for the PDU session to AMF 451. AMF 451 transfers the session context to UE 401 over RAN 420, and AMF 451 and UE 401 may use the quantum communication keys for encryption/decryption of the network signaling. UE 401 uses the context to initiate the PDU session. UE 401 wirelessly exchanges user data with CU 423 over RU 421 and DU 422. CU 423 exchanges the user data with UPF 453. UE 401 and UPF 453 may also quantum communication keys for encryption/decryption of the user data. UPF 453 exchanges the user data with external systems and may use the quantum communication keys for end-to-end security—the quantum communication keys being securely communicated to the end point.

In a similar manner, UE 402 detachably couples to edge UDM 441 in vehicle support station 440 over quantum link 412. Quantum link 412 comprises an optical interface, metallic links, glass fibers, a vacuum, and/or some other type of medium that can transfer or some other type of quantum capable interface that can transfer qubits between UE 401 and edge UDM 431. UE 402 authenticates with vehicle support station 440. In response to the authentication, edge UDM 441 initiates a QKD procedure with UE 402. Edge UDM 441 generates qubits for UE 402. Edge UDM 441 selects a polarization basis for individual ones of the qubits and polarizes the qubits in accordance with their selected polarization bases. Edge UDM 441 transfers the polarized qubits to UE 402 over quantum link 412. UE 402 receives the qubits from edge UDM 441. UE 402 selects a measurement basis for each of the individual qubits received from edge UDM 441. UE 402 determines the polarizations of the received qubits using the corresponding selected measurement basis for each of the received qubits. UE 402 wirelessly indicates the determined polarizations of the received qubits to edge UDM 441. Edge UDM 441 wirelessly indicates the polarizations it selected for each of the transferred qubits to UE 402. Edge UDM 441 and UE 402 generate an authentication key for UE 402 based on the determined polarizations of the received qubits and the selected polarizations for the transferred qubits. Edge UDM 441 transfers the authentication key for UE 402 to UDM 455 over a classical communications channel. For example, edge UDM 441 may encrypt the quantum authentication key for UE 402 using a 5GC cryptography protocol and transfer the quantum authentication key to UDM 455 over a secure classical channel.

In some examples, UEs 401-402 may lack the ability to process and determine polarizations of qubits. In this case, drone landing platform 430 and/or vehicle support station 440 identify the qubit polarizations for UEs 401-402 and indicate the polarization states to UEs 401-402. UEs 401-402 may use the indicated polarizations to derive their quantum-based authentication keys.

To generate communication keys, edge UDM 441 initiates another QKD procedure with UE 402. Edge UDM 441 generates additional qubits for UE 402. Edge UDM 441 selects a polarization basis for individual ones of the additional qubits and polarizes the additional qubits using their selected polarization bases. Edge UDM 441 transfers the additional polarized qubits to UE 402 over quantum link 412. UE 402 receives the additional qubits from edge UDM 441. UE 402 determines the polarizations of the additional qubits. UE 402 wirelessly indicates the determined polarizations of the additional qubits to edge UDM 441. Edge UDM 441 and UE 402 generate communication keys for UE 402 based on the determined polarizations of the additional qubits. UDM 441 transfers the communication keys for UE 402 to UDM 455 over the secure channel. UE 402 detaches from vehicle support station 440 and moves to another location.

CU 423 transfers a registration request for UE 402 to AMF 451. AMF 451 transfers an identity request to UE 402 in NAS signaling over RAN 420. In response, UE 402 indicates its identity to AMF 451 over RAN 420. AMF 451 selects AUSF 454 to authenticate UE 402 for wireless services and transfers an authentication request for UE 402.

AUSF 454 selects UDM 455 to authenticate UE 402. AUSF 454 requests authentication keys for UE 402 from UDM 455. UDM 455 transfers authentication data for UE 401 that indicates the quantum derived authentication key to AUSF 454. AUSF 454 uses the quantum derived authentication key for UE 402 and a random number to generate an expected result. AUSF 454 transfers the random number and the expected result for UE 402 to AMF 451. AMF 451 transfers the random number for UE 401 to over RAN 420. UE 402 hashes the random number with its quantum derived authentication key to generate the same expected result. UE 402 transfers the expected result to AMF 451 over RAN 420. AMF 451 matches the two expected results to authenticate the identity of UE 402.

Responsive to the authentication and authorization, AMF 451 retrieves UE context for UE 402 from UDM 455. AMF 451 retrieves retrieve service policies for UE 402 from PCF 456.

AMF 451 and UE 402 may use the quantum communication key for UE 402 for encryption/decryption of network signaling. UE 402 uses the context to initiate the PDU session. UE 402 wirelessly exchanges user data with UPF 453 over RAN 420. UPF 453 and UE 402 may use the quantum communication key for UE 402 for encryption/decryption of user data.

UE 402 may comprise similar architecture to UE 401, however UE 402 may be different. UE 401 comprises 5G radio 501, quantum circuitry 502, and user circuitry 503. Radio 501 comprises antennas, amplifiers, filters, modulation, analog-to-digital interfaces, Digital Signal Processers (DSP), memory, and transceivers that are coupled over bus circuitry. Quantum circuitry 502 comprises an optical port, a qubit receiver, and transceivers that are coupled over bus circuitry. User circuitry 503 comprises memory, CPU, user interfaces and components, and transceivers that are coupled over bus circuitry. The memory in user circuitry 503 stores an operating system (OS), user applications (USER), Quantum Applications (Q-APP), and 5GNR network applications for Physical Layer (PHY), Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), Service Data Adaptation Protocol (SDAP), and Radio Resource Control (RRC). The antenna in radio 501 is wirelessly coupled to 5G RAN 420 over a 5GNR link. The quantum interface in quantum circuitry 502 is coupled to edge UDM 431 over quantum link 411. A transceiver in radio 501 is coupled to a transceiver in user circuitry 503. A transceiver in quantum circuitry 502 is coupled to a transceiver in user circuitry 503. A transceiver in user circuitry 503 is typically coupled to the user interfaces and components like displays, controllers, and memory.

In radio 501, the antennas receive wireless signals from 5G RAN 420 that transport downlink 5GNR signaling and data. The antennas transfer corresponding electrical signals through duplexers to the amplifiers. The amplifiers boost the received signals for filters which attenuate unwanted energy. Demodulators down-convert the amplified signals from their carrier frequency. The analog/digital interfaces convert the demodulated analog signals into digital signals for the DSPs. The DSPs transfer corresponding 5GNR symbols to user circuitry 503 over the transceivers. In user circuitry 503, the CPU executes the network applications to process the 5GNR symbols and recover the downlink 5GNR signaling and data. The 5GNR network applications receive new uplink signaling and data from the user applications. The network applications process the uplink user signaling and the downlink 5GNR signaling to generate new downlink user signaling and new uplink 5GNR signaling. The network applications transfer the new downlink user signaling and data to the user applications. The 5GNR network applications process the new uplink 5GNR signaling and user data to generate corresponding uplink 5GNR symbols that carry the uplink 5GNR signaling and data.

In radio 501, the DSP processes the uplink 5GNR symbols to generate corresponding digital signals for the analog-to-digital interfaces. The analog-to-digital interfaces convert the digital uplink signals into analog uplink signals for modulation. Modulation up-converts the uplink analog signals to their carrier frequency. The amplifiers boost the modulated uplink signals for the filters which attenuate unwanted out-of-band energy. The filters transfer the filtered uplink signals through duplexers to the antennas. The electrical uplink signals drive the antennas to emit corresponding wireless 5GNR signals to 5G RAN 420 that transport the uplink 5GNR signaling and data.

In quantum circuitry 502, the optical port couples to one of edge UDM 431 over the quantum link 411. The quantum interface receives qubits from edge UDM 431 and passes the qubits to the qubit receiver. The qubit receiver determines the polarizations for the received qubits using measurement bases indicated by the Q-APP. The measurement bases used by the qubit receiver may be selected by the Q-APP at random, semi-random, or may be pre-defined. Typically, the selected measurement bases are chosen in a secure manner so that they remain private to the UE during key generation. The qubit receiver indicates the determined polarizations to user circuitry 503 over the transceivers.

The Q-APP in UE 401 and edge UDM 431 exchange the polarization states determined by the qubit processor and the polarization states that the edge UDM encoded the qubits with. The Q-APP UE 401 and the edge UDM may wirelessly exchange the polarization states over 5G radio 501 or quantum circuitry 502. The Q-APP compares the determined polarization states and the polarization states that the edge UDM encoded the qubits with. The Q-APP identifies qubits that have a determined polarization state that is the same as the encoded polarization state. Typically, around 50% of the qubits will have polarization states that will be the same. The Q-APP generates an authentication key based on the qubits with matching polarization states.
